REDUCING PRODUCT DEFECTS IN APPAREL MANUFACTURING BY USING THE SIX SIGMA METHODOLOGY: A CASE STUDY

Six Sigma is a statistical methodology aiming to reduce and preclude failures in business processes. Its the foremost principle is that once the number of refuses in any process is discernible, the procedures can be established to systematically prevent them. This paper reports a performance of an implementation of the Six Sigma Methodology in an apparel plant, that has provided an increase of 13% in the manufacturing productivity of trousers by minimization of sewing thread breakage. This accomplishment has been obtained by reducing the thread breakages in the process of the sewing trademark label to the rear center of a trouser.
